Two Espressos Enhance Long-Term Memory
More evidence of the effect of caffeine delivered via espresso shots has been found in a recent study led by Michael Yassa from the University of California, Irvine. Yassa sought to establish the effects of small quantities of caffeine on memory function in adults, and gave participants caffeine pills equivalent to two shots of espresso. The results from making participants view different pictures and recall similar images was better in those who had the caffeine.
Yassa concluded that caffeine enhances long-term memory by improving the process of memory consolidation, but caffeine doesn't help memory retrieval. Yassa did a second experiment, where caffeine was consumed just one hours before the test, and it provided no positive effect. Yassa also tried using less caffeine and the results were less pronounced—so two espressos is the real sweet spot.
We’re off to get our second shot of espresso right now, and we’re pretty sure we’ll be able to recall the different blends of similar K-Cups over the next few hours.
